Outcome Measures
Primary Outcomes (1)
Improvement of subjective perception of dry mouth as measured on the Visual Analog Scale
The primary outcome is defined as the proportion of patients reporting a 30% reduction of xerostomia symptoms as evaluated through a 100mm VAS (100mm=maximum dryness).
12 month
Secondary Outcomes (5)

Eligibility Criteria
You may qualify if:
- To be at least 18 years old
- To have received more than 40 Gy of external beam RT for cancer in the H\&N region at least 4 months before entry into the study
- To have grade 1 or 2 of RTOG/EORTC Late Radiation Morbidity Scoring Schema
- To have a degree of minimum degree of dryness of 50mm (≥50mm) on a 100mm VAS scale (0=no dryness; 100
- =maximum dryness).
- To have demonstrable residual salivary gland function (increase in salivary flow on appropriate stimulation (e.g. chewing paraffin wax)
- To have at least one parotid gland
You may not qualify if:
- To have severe uncontrolled systemic disease (on the basis of the classification of the American Society of Anesthesiology: ASA IV and ASA V)
- To have known allergy to materials similar to those used in the investigational product
- To wear other active implants such as cardiac pacemaker or defibrillator, or hearing aids
- To have an unstimulated whole salivary flow of 0ml/15min (complete absence of unstimulated salivary flow as measured via sialometry for 15 minutes).
- To use of pilocarpine as systemic therapy
- To have grade 3 RTOG/EROTC or no resting saliva (sialometry = 0mL/1.5 min)
- To have no parotid glands
